Hi all, thanks in advance for any help.

I received cleared notifications for voltage sag events that lasted less than 60ms. I did **not** receive an active notification for this event. The alarm configurations are using a 5 second on/off delays so an alarm should have never been generated. I also have no history of the event in either the alarm journal or the tag history. The device that triggered the event is SEL 735 meter using a DNP3 connection.

There were four events total, at two different sites. Phase A events lasted ~60ms while Phase B events lasted ~35ms. All look the same so I will post the images of one event.

The voltage sag event on phase B lasts ~35 ms as captured by the SEL 735 meter:

There is no active notification in Slack but a cleared notification is received which states the active alarm duration is 2ms:

When I search the time listed in the notification there is no correlating journal entry:

When I view the tag history there is no record of the Boolean tag going high:

I'm trying to understand how these events have slipped through and triggered notification. Any insight is greatly appreciated.

> There is no active notification in slack ...

What does this mean? Is slack a brand name ('Slack' capitalised) or something else?

> ... but a cleared notification is received ...

Received by what?

It's not clear what the problem is here.

Thanks for the response.

Apologies, Slack is a messaging service being used by the client. Each site has it's own channel. We're sending alarm notifications to Slack channels using a webhook URL.

The main issue is that the alarm events ignored the ON/OFF delays of 5 seconds. There should have never been an alarm event. Looking at the meters data confirmed the event was real. In Ignition I have no record of this alarm becoming active or of the tag changing state.

The only have a record I have of this event from Ignition is receiving notification that the alarm state had cleared. But I never received a notification that the alarm went active.

Hope that clarifies.
